GOMEZ, Germán; VELEZ, Consuelo; CEBALLOS, Alejandro  and  HENAO, Francisco J. Systematic Review of Factors Associated with the Presence of Cytoplasmic Droplets in Boars. Rev. salud pública [online]. 2014, vol.16, n.6, pp.937-946. ISSN 0124-0064.  https://doi.org/10.15446/rsap.v16n6.44146.

Objective To determine the factors associated with the presence of cytoplasmic droplets in boars. Methods A systematic review was carried out in which 133 articles were found, 70 were eliminated due to duplication, and 65 were finally selected: 57 in Cab Abstract, 39 in Pub Med, 20 in Agricola, and 17 in Science Direct. Forty-seven articles were found with an available full text. Data was tabulated in EpiData Entry and transferred to the Stata version 12.0 program. Results Factors Associated with cytoplasmic droplets are: Climatic and environmental variables; ejaculation frequency with intervals of less than three weeks; spermatic morphologic alterations in tail (coiled and distal reflex); DNA fragmentation; and enzymatic factors related to seminal biochemistry. Work carried out in equatorial climate regions or that focused on the analysis of the implications of CDs in artificial insemination centers was not found. Conclusions The information is characterized by a wide heterogeneity and diversity studies. A contribution was made to Veterinary Public Health in Colombia on the importance of CGs as factors that limit reproductive processes in swine. It was not possible to determine the temporal relationship between the cause and effect of CDs.

Keywords : Spermatozoa; epidemiologic factors; insemination; artificial systematic review.
